Power relays, as an important component in electric industry, have a wide range of applications in many areas. PT2S7LB2 is one type of power relay, and it is applied for controlling current more than 2 amps. This article will introduce the application field and working principle of PT2S7LB2.
Application Field
As its rated current is over 2 amps, PT2S7LB2 is usually applied to areas where high current is required. It has a wide range applications, such as controlling electromechanical devices, switching and distributing of high current and signaling in audios, and so on. PT2S7LB2 is well-known for its rugged and reliable construction, and it has high quality requirement due to its application in the areas of high current.
Working Principle
PT2S7LB2 is an electromagnetic relay, and its working principle is similar with other relays. The relay consists of two parts, the main part contacts, and the control part. When the control part is actuated, it will generate a magnetic field which attracts the main part contacts. As the main part contacts are attracted, the switch contacts in the main part will be closed and the current will be connected. Then the control part will reset the main part contacts, and the switch contacts will open and the current will be disconnected.
Conclusion
PT2S7LB2 is an important type of power relay with ratings over 2 amps. It has a wide range of applications and its working principle is controlled by the magnetic field generated by the control part. With its rugged and reliable construction, it has high quality requirement and it is widely used in the areas where high current is required.
